If this card is sent to the Graveyard: You can Special Summon 1 Dragon-Type monster from your hand. You cannot Special Summon monsters, except Dragon-Type monsters, nor conduct your Battle Phase, the turn you activate this effect. You can only use this effect of "Kidmodo Dragon" once per turn.
Special summoning Apocralyph using Kidmodo will let you summon it in defense position, preventing you from taking damage if it gets attacked. On your turn, you will be able to activate Aporcralyph's effect to return Kidmodo back to your hand.
If Kidmodo gets destroyed during your opponent's battle phase, you can special summon Darkstorm from your hand, and normal summon it on your next turn. This will enable his effect so you can destroy all spell/trap card your opponent controls.
You can bring more Kidmodo in your deck, or use Dust Knight instead. Use the flip effect when it gets attacked instead of flip summoning this card, so you can still conduct your battle phase, or special summon other Dragon monsters.
Summoning high level normal Dragon-type monsters can be a good option as well. Combine this with Champion's Vigilance so you can get an early control over your opponent's actions.
